|Higher Taxa||Scincidae, Scincinae, Scincoidea, Sauria, Squamata (lizards)|
|Synonym||Plestiodon nietoi FERIA-ORTIZ & GARCÍA-VÁZQUEZ 2012|
|Distribution||Mexico (Guerrero: Sierra Madre del Sur)|
Type locality: La Llave, El Balcón, Ajuchitan del Progreso, Guerrero, México (17° 37’ 21.9’’ N, 100° 34’ 29.3’’ W) at 1831 m elevation.
|Types||Holotype: MZFC 22249 (original number JCBH 115), an adult male, collected by Jean Cristian Blancas Hernan- dez on 05 February 2007|
Paratypes. Twelve specimens, all from Ajuchitlan del Progreso municipality, Guerrero, Mexico: three from the same locality as the holotype (MZFC 22250–22252); two from El Filo, El Balcón (MZFC 22247–22248); two from El Moreno, El Balcón (MZFC 22253–22254); and five from road La Ola-San Antonio Texas (UTA-R 58460- 58464).
|Diagnosis||Diagnosis. Plestiodon nietoi sp. nov. can be distinguished from all other species of the P. brevirostris group by large adult body size (up to 77 mm maximum SVL in P. nietoi sp. nov. vs. 73 mm maximum SVL in the other spe- cies; Table 1). In addition, P. nietoi sp. nov. can be distinguished from P. ochoterenae, P. parviauriculatus, P. copei, P. brevirostris, and P. dicei by having the interparietal enclosed posteriorly by parietals in most specimens (91.7% in P. nietoi sp. nov., 0–11.8% in all other taxa), and from P. bilineatus, P. dicei and P. indubitus by having a pale lat- eral line on the neck (absent in the other subspecies and replaced by a series of scales that have white anterior edges and centers with black posterior borders, on longitudinal scale rows 5–9 or any combination of these rows in sequence on P. indubitus). Plestiodon nietoi sp. nov. can be distinguished from P. dugesii by having four supraocu- lars (vs. three in P. dugesii). Furthermore, P. nietoi sp. nov. differs from P. parvulus and P. copei by having the seventh supralabial in con- tact with the upper secondary temporal (absence of contact in P. parvulus and P. copei), from P. colimensis by having fewer scales encircling the body (21–23, x = 22.1, n = 13 in P. nietoi; 27–28, x = 27.5, n = 2 in P. colimensis) and more body scales than P. parviauriculatus (19–20, x = 19.9, n = 14). Additionally, P. nietoi sp. nov. may be dis- tinguished from P. brevirostris, P. dicei, and P. copei by fewer paravertebral scales (47–51, x = 50, n = 13 in P. nie- toi sp. nov., 52–58, x = 56.0, n = 38; 48–60, x = 55.3, n = 46; and 53–61, x = 56.6, n = 35, in P. brevirostris, P. dicei, and P. copei, respectively) [from FERIA-ORTIZ & GARCÍA-VÁZQUEZ 2012].|
